USB Solar Chargers and powerbanks are a very handy addition to your camping-touring entourage.
Both can be light, packable, and do exactly what you want them to do.
The basic solar charger has a slow charging, single USB socket but as you pay more, you'll be able to charge faster and connect two USB devices at once. Best idea, if you are heading for the sun, is to strap the charger to your backrack and let your panels trickle charge a powerbank and phone through the day then charge your garmin with the powerbank overnight. The more wattage eg 11W 15W etc etc - the faster the charge but the heavier and more expensive they become.
USB Powerbanks - the lower the mah, the slower and lesser the charging capabilities. A 2000mah device may keep your phone topped up but not be able to fully charge it from 0%. 10000mah could charge the phone three times. The lower the ma, the cheaper, lighter and smaller.
They seem to start at a tenner for 2000mah/3500mah and get pricier as you move into to 10000mah+.
The PortaPow is very light - about 300g or so - and is ideal for strapping to your back rack. Folds up neatly for packing away as well.
There are plenty of solar chargers and powerbanks out there - get browsing and go green!Do your research!
